I am trying to build a Clone of the Godbout S-100 Terminator
for my
Byte-8 Box.
Looks like Unicorn may have what I want
Thanks for all the replies

I am Looking for a LM4250H 8 Pin DIP or A real
good substitute. I found
a Data Sheet but having trouble locating any Parts. I am hoping someone
has one in their Parts Box TIA Bob in Wisconsin USE trebor07 at execpc.com
My cross-reference charts say that the TI OPA704PA (in current
production and available from Digi-Key) is a drop-in substitute. The
Philips ECG944M may also work.

I have several NOS LM4250CN, date code 8121.
The CN in plastic 8-pin DIP, 0C to +70C.
According to the NS book, the H is metal can, -55C to +125C.
Can throw a couple in the mail from Vancouver, Canada, if you don't find
anything faster/closer.
What's the app?, does it really have special requirements? So many op-amp types
have been produced over the years. Perhaps I exagerrate, but they seem like
transistors in that a dozen modern types could cover substitution for the
entire range of types.
